There is one thing about your channel, Research, when you do a video it is strongly based in research, the conclusions you have are supported with that as a foundation, (I TRUST YOUR CHANNEL). also, your experience, your trial and error, your knowledge of Hand crafting ammunition and again research of load books, Manuals, and personal experience offered from expert firearm journals makes your show not just someone's Opinion which is a belief or judgement and that's where it starts and ends. You provide great content, (BTW) I casted the 314299 mold using linotype, I seated the gas checks, then with a little film a lube ran then through my RCBS Lube sizer to crimp the gas checks and size them to .314, I removed the lube and then powder coated them, then back to the lube sizer to apply lube in the lube bands. I loaded them with 25 grs of IMR 4227, they grouped within a inch @100 yards with my No#4 Mk-2. That is a excellent bullet. I wish I had your email address so I wouldn't take up so much of your comment space. Peace dude - Dave

Thanks for the kind words Dave. I need to go over to the Facebook 314299 page and see if I can find your email and pass along my email address to you.

Your bench top reviews are the best. As long as you keep breaking down ammo, I'll keep watching

[@nickglass12]

Very thorough analysis as always. Thanks!

Thanks.

Good description. Thank you.

Neat stuff. Thank you for sharing.

[@markworden9169]

Thanks, have not been here lately but see you have some 30 30 cast bullet videos that I'll research.

[@314299]

I do have a few 30/30 cast videos, I hope you find them interesting.

[@xjda68]

Also, I forgot to mention. Yes, you are correct in your assumption the number 5 if for the month of May. These headstamps run from 1 - 12.

[@xjda68]

Povazske Strojarne, Bystrica, Slovakia. CSSR State run under communist rule at the time this ammunition was made. Clandestine headstamp made for Israel. Yes, the Star of David just indicated brass case, same as an asterisk that was also used. As a + symbol indicates steel case. If there is a line after the factory code, then that indicates only one offset Berdan flash hole. Drill bits cost money, as these small flash holes are dilled. The "X" is just a clandestine symbol that was used. They also used a male symbol, 4 dots and a few others on military cartridges during the same time period. The WWII German code given to this factory to use was P14A and changed to dou the fist of 1941. The Czech military headstamp used at that time was a letter Z. This factory moved a couple of times so there are many codes used. Lots of owners over the years since 1866. You do nice videos. Thanks, Joe Long time cartridge collector.

Hi Joe, thanks for that valuable and interesting input!

I have a few 50 BMG slugs well the inner mild steel center that was left from being shot through what looked like 1/2” thick steel plate. And that mild steel 50 BMG inner looks EXACTLY like those 8mm slugs. With the wasp body shape and everything. I have read in forum posts that guys use the 50 core as a center punch??? But I don’t know how the ones I have are exactly as described mild steel that are very soft. I tried to use one as a center punch and it rounded the tip right over. So I decided to see if I could make it sharp again with a file and it was so easy to file it. Just goes to show you a guy definitely can’t believe what is written on the Internet.

[@314299]

50 BMG has been made so long and in so many place there are no doubt variations on the material used for cores for the bullets. The Germans did make a version of 8mm steel core ammo with a hardened core for some armor piecing ability.

[@Dalwhinnie15]

I had some of that a few years ago that I bought at a gun show. Shot it all, though.

[@lpalerme]

Thank you for a very interesting and thorough presentation. Does firing this type of steel jacketed ammo negatively affect barrel life ?

[@314299]

It does not seem to be especially hard on barrel life. The jackets are annealed to make them much softer than the barrel steel and the plating on the bullets prevents galling.

[@slowhand1198]

Another reminder to check on my stock. I'm thinking most of my older stuff is Yugoslavian.

[@314299]

The Yugoslavs seem to have made good stuff - any idea how old yours is?

[@slowhand1198]

@@314299 The easily accessible stuff is dated 1953, and is on stripper clips. I'll have to dig deeper and see what the rest is.

[@bigtrev761]

🇦🇺😎👍I haven’t seen any military ammunition down here for many years

[@gloryToTheMelonLand]

I do have 1 of these, but the primer has a mark like it was fired but it is intact like the bullet is still there is it posible for the primer to corode and render the ammo useless? (1943 P 7.62 (unredeable letter)D

[@314299]

If it's from 1943 and failed to go off I would say it's already "useless". Since it did not go off the primer probably was a dud and should have no effect on the powder or case, however since it did not go off you really would have to pull the bullet to investigate if perhaps the powder was also bad.

[@gloryToTheMelonLand]

@@314299 even tho it is a real one i just keep it as decoration and do not have the equipment to put the bullet back in the casing cuz ik i would need to make it tighter( tighten the brass so the bullet stands) and i really dont want to squeeze it with pliers
